The development of precision machining technology plays a crucial role in promoting progress in various industries in modern manufacturing. Water guided laser technology, as an innovative processing method, is gradually emerging and widely applied in multiple fields with its unique advantages.

The principle of water guided laser technology is based on the propagation characteristics of light in different media. It uses water as a light guiding medium and is specially designed to achieve total internal reflection of laser in water flow, just like the propagation of light in optical fibers. This clever combination of laser and water has brought many significant advantages to the processing process.

Reducing the heat affected zone is a prominent advantage of water guided laser technology. In traditional laser processing, high heat can easily cause material deformation, microcracks, and other problems. And water guided laser

In technology, fast flowing water can quickly remove the heat generated by laser processing, controlling the heat affected zone within a very small range. Related studies have shown that the heat affected zone of water guided laser processing can be controlled within 50 μ m, which is significantly reduced compared to traditional laser processing, effectively avoiding the impact of material thermal damage on performance and ensuring the quality and accuracy of the processed parts.

In terms of improving processing accuracy, water guided laser technology also performs well. The water beam guides the laser energy to be evenly distributed, making the cutting seam width extremely narrow, such as 27 μ m, and the surface roughness Ra of the processed surface ≤ 1 μ m. This feature enables it to perform non taper cutting on superhard materials such as diamond and silicon carbide, achieving high-precision machining effects and meeting the high precision requirements of industries such as aerospace and electronic manufacturing.

Water guided laser technology has broad universality in material adaptability. Whether it is metal materials such as titanium alloys, nickel based high-temperature alloys, semiconductor materials SiC and GaAs, or ceramic materials Al ₂ O3 and ZrO ₂, as well as various composite materials CFRP and CMC, it can easily handle them, breaking through the limitations of traditional processes in material processing and providing strong support for the application of new materials and product innovation.

From an environmental and safety perspective, water guided laser technology also has significant advantages. During the processing, the aqueous medium can effectively capture and remove the generated smoke, debris, and harmful gases, avoiding the pollution of the environment and the harm to the health of operators caused by high temperature smoke and metal dust commonly seen in traditional processing methods, and creating a cleaner and safer working environment.

Water guided laser technology has become a shining star in the field of modern precision machining due to its advantages in reducing the heat affected zone, improving processing accuracy, wide material adaptability, and environmental safety. With the continuous development and improvement of technology, it will inevitably play an important role in more fields, promoting the manufacturing industry to move towards higher precision and higher quality.
